Suppose the US Department of Education is interested in knowing if the proportion of high school seniors planning on attending college is not 60%. They conduct a hypothesis test with Alpha = 0.05 and get a p-value of 0.039. What interpretation should they make?
Homework Answers
Answer: SInce the P value is less than the significance level 0.05, we therefore reject the null hypothesis and believe that the proportion of high school seniors planning to attend college is not 60% or 0.60.

A decade-old study found that the proportion, p, of high school seniors who believed that "getting rich" was an important personal goal was 80%. A researcher decides to test whether or not that percentage still stands. He finds that, among the 230 high school seniors in his random sample, 199 believe that "getting rich" is an important goal. Can he conclude, at the 0.05 level of significance, that the proportion has indeed changed? Perform a two-tailed test. Then fill in...

Question 21 3 pts Large Sample Proportion Problem. A survey was conducted on high school marijuana use. Of the 2266 high school students surveyed, 970 admitted to smoking marijuana at least once. A study done 10 years earlier estimated that 45% of the students had tried marijuana. We want to conduct a hypothesis test to see if the true proportion of high school students who tried marijuana is now less than 45%. Use alpha = .01. What is the critical...

A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 75%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported.
